George Takei has called for Star Wars and Star Trek fans to unite against the mutual threat to all science fiction: Twilight.

Star Trek actor Takei released a video message to broker peace in the decade-long feud between Treckis and Star Wars devotees.

Since the Millenium Falcon first arrived on movie screen in 1977, Star Wars fans and supporters of Cpt James T. Kirk and his crew on the USS Enterprise have exchanged bitter words, as to which franchise was the superior one.

But now Takei who played Lieutenant Hikaru Sulu, the helmsman of the USS Enterprise has demanded a ceasefire in the face of a mutual foe: The Twilight franchise.

"Fellow star folks. Cool it down, and shut your big worm holes," said Takei in a video message posted online following the outbreak of a war of words between William Shatner, who played Captain James T Kirk in the original Star Trek Series, and Carrie Fisher, who played Princess Leia in the original Star Wars trilogy.

"Each is wonderful in its own special way so if you don't knock it off you will soon start seeing images like this one on the net," said Takei, referring to an image of Fisher in the grasp of Shatner, who was mocked up to look like the Star Wars character, Jabba the Hutt.

The feud started when Shatner, who claimed that Star Wars was derivative of Star Trek, prompting Fisher to fire back, calling him to a "costume-off", with her appearing in the metal bikini she wore in Return of the Jedi.

Before the intergalactic argument would claim any victims, Lieutenant Sulu rushed in to broker peace.

"What is needed today now more than ever is star peace, for there is an ominous mutual threat to all science fiction," the 74-year-old said.

"It's called Twilight, and it is really, really bad."

"Gone is any sense of heroism, camaraderie, or epic battle. In its place, we have vampires that sparkle, and moan, and go to high school".

"Now I am not above mixing in a little sex appeal to spice up the fantasy," he added, his words accompanied by the appearance of images of a topless young Mr Sulu and Robert Pattinson, the star of Twilight.

"But sci-fi fans be warned. There are no great stories, characters or profound life lessons to be had in Twilight. No, in Twilight, the only message that rings through loud and clear is 'Does my boyfriend like me?'"

"Let us band together to combat this mutual threat. On my part, I have written to some friends hoping they can help us rid the world of this vampire menace. Buffy, Blade, it's up to you now," said Takei, as images flashed up showing the two named fictional vampire killers.

"So Starfriends, let us live and let live, long and prosperously, and may the force be with you always."

Takei voiced Lok Durd in Star Wars: The Clone Wars, making him the only cast member from the original Star Trek series to also have a role in the Star Wars franchise.
